VEHICLE-WHEEL.

Specification of Letters Patent.

Application filed October 4, 1920. Serial No. 414,422.

To all whom it may con cern Be it known that I, J orm Jomscn, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in VehiclelVheels, of which the following is a specification, reference being had therein to the accompanying drawings.

The primary object of my invention is to provide a resilient wheel with a-yieldable periphery or tread which will ,aii'ord a eushionfor-the body of the wheel during its use, and within the body of the wheel are novel means for resisting the yieldableness of he periphery or tread, with said means constructed so that it may be adjusted for various loads, thus permitting of the wheel being used for'light. and heavy vehicles to provide a desired degree of yieldableness between the road and the body of the vehicle,

Another object of my invention is to provide a" wheel having novel tire support ng or suspending members. which w ll obviate the necessity of using a pneumatic t1re, inflated members, spring spokes, and devices heretofore tried out or used.

A further object of this invention is to provide a' resilient wheel with radiating tread members constantly maintained dis-. tended by axially disposed means within the body or hub portion of the wheel, said means resisting compression of the tread members without interfering with the turning of the wheel about. its axis. 1

A still further object of this invention is to accomplish the above results by a durable construction that will be hereinafter specifically described and then claimed, and reference will now be had'to the drawings,- wh'erein- Figure l is a ,side elevation of the wheel partly broken away and partly in section;

Fig. 2 is a transverse sectional view of the wheel partly in elevation;

Fig. 3 is a detail sectional view of a portioh of the wheel, showing a wrench adapted for adjusting the tensionmeans of the wheel;

5115] .In the drawing the reference numeral 1 denotes a hub having an opening 2 adapted to receive the spindle or end of an axle (not shown) ()n the inner end of the hub 1 is a peripheral flange 3 and extending from this flange to the outer end of the hub are a screw threaded ends 9' of coiled"re-tractile sprni 10, said springs having the inner co'nvo utions. thereof anchored in the flange 3, as at 11,. andthe retractile force of these springs is adapted to resist an outward movement of the sleeve 6 on-the hub l.

The outer ends of the rotatable nuts 8 terminate in pinions or small gear wheels 12 and adapted to be placed in engagemen'tWi-th these pmions or small gear wheels is a large gear wheel 13 forming part ofa-cap Wrench 14 which may be placed over the end of the hub 1 and rotated to simultaneously rotate all of the nuts 8 and increase or decrease the tension of the springs 10 vby the screwthreaded ends 9 thereof moving in the nuts 8.

Mounted between the flanges 3-and 7 and surrounding all of the, springs 10 is a casing 15 which cotiperates with said flanges and the sleeve 6 in providing an inclosure or casing for said springs, the-casing-beingreciprocable on the hub 1 to and from the flange p thereof.

On the casing 15 is a peripheral flange 16 provided with a plurality of radial slots 17 Extending transversely. of the slots 17 are roller pins 18 provided with anti-frictional Patented Mar. 8,1921.

rollers 19 within the slots 17, said pins bea 'ing partly set in the flange 16 and rehained in engagement therewith by plates oi." .Jlocks 20 secured by screw bolts 21 or other fas. tening means mounted in the flange 10.

The body of the'wheel is formed by an inner disk 22 and an outer disk 23, said disks being pressed to provide a housing about the casing 15 on the hub 1. The inner disk 22 is mounted on the inner end of the hub 1, and suitably secured to said disk is a brake drum 24. The outer disk 23 has a concentric opening25 normally closed by a detachable cap 26, said cap permitting of access being had to the outer end of the hub 1, so that the wrench 14 may be used and the hub 1 mounted on an axle spindle.

tread members have The peripheral edges of the disks 22 and 23 are connected by equally spaced bolts 27 and nuts 28 and the peripheral edges are pressed and shaped to afford radially disposed sockets 29 for bushings 3Q which are clamped between said disks. Slidable 111 the bushings 30 are short spokes or stems 31 of tread members 32, said tread members being dctachably connected to the spokes or stems. as at 33, and provided with resilient tread pieces or cushion members 34. The inner ends of the spokes or stems 31 have angularly disposed slotted heads 35 extending into the slots 17 with the antitrictional rollers 19 in the slots of the heads 35, so that inward movement of the tread members 32 will cause the casing 15 to shift outwardly, relative to the flange 3, against the retractile force of the springs 10, and it is these springs that cushion the body of the wheel when supporting a load.

As illustrated in Figs. 4 and 5 the tread members may take the form of gripping heads-l6 to frictionally engage a rim 3? siuiporting a tire 38. The inner 'all of the rim 37 may be toothed or roughened, as at-- 3!), so that the gripping heads 36 may hold the rim 3? for movement with the body of the wheel, and the rim is supported by side plates 41) formed integral with the disks 22 and 23 forming the body of the wheel. Assuming that the wheel supports a load the lowermost gripping heads 36 will remain in engagement with the rim 3'? while other gripping heads are retracted. relative to the rim. due to the load supported by the body of the. wheel. In the preferred 'form of construction all oflhe tread members are simultaneously retracted and this'is also true in the modified form of construction,

but the rim 37 and its tire 38 remain intact and dirt, dust and other foreign matter are excluded by the side plates extending on to the rim or tire of the. wheel.

In the preferred form of construction the the action of individual ground grippers. for instance, as found in connection with caterpillar tractors. and the wheel may be so used for heavy vehicles or provided with the rim and tire for light vehicles. Tn either instance the tension means within the body of the vehicle may be regulated for such use or it may be regulated to compensate for jars and shocks that would ot-herwisebe imparted to a vehicle body when encountering rough and irregular roads.

lVhile in the drawings there are illus trated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

'hat I claim is 1. In a resilient vehicle wheel, a hub, a reciproeable casing on said hub, means in said casing to resist reciprocation of said casing, 21 wheel body inclosing said casing, spokes slidable in said wheel body, tread members on the outer ends of said spokes, and means articulating said spokes and said casing so that inward movement of said spokes is resisted by said casing.

2. A vehicle wheel as in claim 1. characterized by the first mentioned means including springs connecting said hub and easing.

3. A vehicle wheel as in claim 1, characterized by the last mentioned means including anti-frictional rollers supported by said casing, and heads on said spokes engaged by said rollers.

4. in a vehicle wheel. a hub, ci 'irocable thereon. radially shiftable tread members about said casing, means in said casing to resist shifting of said tread members, and means supporting said tread members relative to said'hnb and easing.

5. A vehicle wheel as in claim 4. characterized by said resisting means including springs disposed longitudinally about said hub and adapted to have the tension thereof regulated at the outer end of said hub.

(l. A vehicle wheel as in claim 4 characterized by said resisting means including springs attached to said hub, and rotatable nuts carried by said casing and adapted to be simultaneously rotated to increase or decrease the tension of said springs.

7. in a vehicle wheel, a hub. a wheel body on said hub, shiftable spokes-extending into said wheel body, tread members on the outer ends of said spokes, a rim about said tread members, and means shiftahle longitudinally of said -hub adapted to resist inward movement of said spokes. said means including a spring held casing on said hub. slotted heads 'on said spokes. and anti-frictional rollers carried by said casing and engaging in said spoke heads.

in testimony whereof I atiix my signature in presence of two witnesses.
